Using machine learning approaches for multi-omics data analysis: A review
Open accessAbstract
With the development of modern high-throughput omic measurement platforms, it has become essential for biomedical studies to undertake an integrative (combined) approach to fully utilise these data to gain insights into biological systems. Data from various omics sources such as genetics, proteomics, and metabolomics can be integrated to unravel the intricate working of systems biology using machine learning-based predictive algorithms. Machine learning methods offer novel techniques to integrate and analyse the various omics data enabling the discovery of new biomarkers. These biomarkers have the potential to help in accurate disease prediction, patient stratification and delivering of precision medicine. This review paper explores different integrative machine learning methods which have been used to provide an in-depth understanding of biological systems during normal physiological functioning and in the presence of a disease. It provides insight and recommendations for interdisciplinary professionals who envisage employing machine learning skills in multi-omics studies.

Written from the paper’s full text.
TL;DR
This review surveys machine learning approaches for integrating multi-omics data, organizing methods into concatenation-, model-, and transformation-based strategies for supervised and unsupervised learning. It provides background, application examples, challenges, and a recommendation flowchart for interdisciplinary method selection.
Key findings
- Multi-omics integration methods are grouped into three main classes: concatenation-based, model-based, and transformation-based, each with distinct advantages and disadvantages for combining omics data.
- The review reports that most multi-omics studies focus on cancer, especially breast and ovarian cancer, and that integration can improve understanding of disease complexity beyond single-omics analysis.
- It cites examples including an ADNI study using neuroimaging, biochemical, and genetic biomarkers to discriminate early Alzheimer’s patients from healthy volunteers with 98% accuracy, and notes class imbalance examples such as primary hypertension at 95% prevalence versus endocrine hypertension at 5%.
- A recommendation flowchart is proposed to help interdisciplinary teams choose an appropriate integration method, but the paper states that no “one-size-fits-all” approach is feasible.
Methods
- Narrative review of supervised and unsupervised ML strategies for multi-omics integration, explicitly excluding reinforcement, hybrid, multi-view, and self-supervised learning because they have not gained enough momentum in multi-omics analysis.
- Summarizes integration methods, published multi-omics studies, ML terminology, algorithms, and advantages/disadvantages in tables, and presents a recommendation flowchart.
- No primary dataset or experimental analysis is reported; the paper synthesizes existing literature and examples.
Limitations
- The authors state that existing literature does not provide many direct comparisons between methods using the same publicly available datasets, and that empirical investigation guided by ML practitioners is recommended.
- The review’s scope excludes several emerging ML specializations, including reinforcement, hybrid, multi-view, and self-supervised learning.
- Evident from the text: this is a narrative review without a systematic search protocol or quantitative synthesis, and the provided version is a journal pre-proof with production artifacts.

“Health-based big data including linked information for patients, such as their clinical data (for example gender, age, pathological and physiological history) and omics data (such as genetics, proteomics and metabolomics) has now become more widely available (Canuel et al., 2015;Singhal et al., 2016).”

What the sources say
- Supportedcites Canuel et al., 2015 source
The Introduction describes a growing amount of omics data and the use of clinical data warehouses, while the Conclusion refers to an “explosion of data available” for work combining clinical and omics data. The paper therefore supports the broad claim of increasing availability, without implying that patient-level clinical and omics records are already routinely linked. (LLM, conf=0.86)
- Could not verifycites Singhal et al., 2016 sourceExperimental — accuracy not yet measured
The Introduction discusses using patients’ genetic mutations in precision medicine and curating genotype–phenotype information from biomedical literature. The Methods describe extracting information from PubMed abstracts. Neither section says that linked patient clinical and omics data have become more widely available (searched for availability of clinical, genomic, proteomic and metabolomic data). (LLM, conf=0.75)

The Conclusions (page not provided) report that different classifiers show distinct performance patterns as the number of features changes. This supports the attributed point that commonly used machine-learning algorithms differ in their characteristics; the multi-omics recommendation is the citing authors’ application of that point. (LLM, conf=0.90)

Section 3.2 (p. 15) contrasts decision trees’ transparency and generalization properties with those of other models. Section 4.2 (p. 21) likewise distinguishes interpretable models from models requiring additional explanation. These passages support the attributed point that commonly used ML algorithms have different attributes; the separate recommendation about multi-omics analysis is not part of the quoted claim.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
